SASH-ROD FOR CURTAINS.

Application filed April 7, 1919.

To all whom it may concern Be it known that I, CARL EMIL MoLLnn, a citizen of the United States, residing at the city of Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Sash-Rods for Curtains, of which the following, taken in connection with the accompanying drawings, is a specification.

The invention relates to'sash rods for ourtains; and the object of the improvement is to provide a simple, extensible construction of sash rod for curtains which may be quickly and easily adjusted on the window frame or sash in such a manner that it is held firmly in position, while at the same time it may be as quickly and easily removed therefrom, the extensible length adjusting itself automatically as the ends are attached; and the invention consists in the novel features and combinations hereinafter set forth and claimed.

In the drawings, Figure 1 is a plan view of the under and inner side of the sash rod showing the construction and arrangement of the same. Fig. 2 is a side elevation of the sash rod. Fig. 3 is an elevation of a portion of the inner end looking toward the inner side of the bend and continuation of the rod at section line 3-4 in Fig. 2; and Fig. 4 is a similar sectional view at line 841 in Fig. 2 looking toward the attaching end of the curtain rod. Fig. 5 is a lengthwise sectional view of the end of the curtain rod in position for slipping over the screw head, with the attaching screw just entering the key hole slot and the arrows showing the direction of movement. Fig. 6 is a similar lengthwise sectional view showing the curtain rod before attachment, and, in dot ted outline, after attachment to the holding screw.

Like characters of reference refer to corresponding parts in the several views.

The numeral 10 designates the outer telescoping portion of the curtain rod and the numeral 11 the inner telescoping portion of said rod, which portions are arranged to extensibly adjust the length of the red by slipping backward and forward within one another in the overhanging or tubular edges which have the lengthwise slot 13 therebetween on one side of the rod.

The tubular edges 12 are preferably crimped inwardly as shown at 14 in the rounded end bends 15 thereby greatly Specification of Letters Patent.

strengthening said end bends and rendering .it easier to bend the same into the desired shape. The part 10 fits sufficiently close over the part 11 so that the edges 12 as they spring upon each other in the sliding telescoping action hold the twoparts in relation to one another with suiiicient firmness for allpractical purposes.

, ,The bent ends 15 areturned inward to form the attaching ends 16 which attaching ends 16 are preferably in the same plane as the surface to which they are to be attached and have the key hole slot 17 therethrough to receive the head of the screw 18 in holding engagement therein. For convenience and to give added stiffness the crimped edges are flattened against each sideof each end 16, thereby strengthening the entire construction and giving a pleasing finish thereto. The key hole slot 17 has the projecting lip 19 around the enlarged end of the same to guide the head of the screw 18 into said key hole slot 17, it being apparent that with the inclined inner surface of the lip 19 passing over the preferably round headed screw 18, two curved surfaces are brought into conjunction which perfectly guide the rod end 16 onto the screw 18 within the enlarged end of the key hole slot 17 after which it may he slipped endwise into looking engagement in the narrow end of said key hole slot. When the ends 16 of the two telescoping parts 10 and 11 are thus quickly and easily slipped into locking engagement with thescrew 18, it is apparent that the gurtain rod is held against all sidewise strains, yet may be quickly and easily re moved from the attaching screws 18 by sliding the parts 10 and 11 endwise thereby moving the rod on the heads of the screws 18 into the enlarged portion of the slot 17 and permitting the guiding outward of the screw head from the slot 17 by means of the lip 19 in very much the same manner in which it was guided by said lip in. entering said slot.

It is apparent that the parts of my simple extensible curtain. rod may be quickly and easily assembled by inserting the end of the part 11 into the part 10 and the screws hav ing been placed in the correctly spaced rela tion in the supporting surface, whether in the sash or window frame, with just sufficient room between the head of the screw 18 and said supporting surface to permit the entrance of the sheet metal attaching ends 16 therebetween, said attaching ends may be quickly and easily slipped on to the heads of the screws 18, the lip 19 guiding said screws to place in the key hole slots 17 at each end, thereby providing an exceedingly simple and convenient curtain rod with a strong and durable yet quick and easy attachment to the sash or frame.

I claim as new:

1. In a curtain rod, a pair of telescopic members each having a supporting end, said ends being each formed with a key-hole shaped slot, the outer end wall of the larger part of the slot being turned outwardly to form a lip which lies at an incline and extends toward the slot, and round headed screws having their heads engageable through the larger part of the slot, the inclination of said lips being substantially equal to the curvature of the screw heads whereby the lips act as guides to efifect entry of the screws into the slots.

2. In a curtain rod, a pair of telescopic members each having a supporting end, said ends being each formed with a key hole shaped slot, round headed screws having their heads engage-able through the larger part of the slot, and a lip disposed at the outer end wall of the larger part of the slot,

the lips extending toward the slots and being inclined at substantially the curvature of the screw heads so as to serve as guides to effect entry of the screws into the slots.

In testimony whereof I have affixed my signature in the presence of two witnesses.

CARL EMIL MOLLER.
